AirWard - Kit, Piper MSB 977 - Access Covers (Baggage Compartment) - PA28/32/34/44
Field reports indicate that some Piper aircraft may be experiencing corrosion on the steel rear Wing Attach Fittings. Â It appears that over time, should the seals for the windows and doors NOT be maintained, leaks may develop which, if not corrected, will allow an ingress of water. Â This water contamination will wet the insulation around the rear Wing Spar Attach Fitting creating a highly corrosive environment. Â In addition, inspection access is difficult on some early aircraft in the PA-28 Series and require that inspection access panels be installed to ease inspection in this area.
This Service Bulletin requires the following:
Addition of two Access Panels to the rear floorboard (where required);
Inspection to determine condition of the aircraft window and door seals and, if necessary, the corrective action needed;
A one time inspection to determine the condition of the Rear Wing Attach Fittings;
Inspection of the insulation material around the affected area;
And the addition of drain holes at the aft attach fitting area.
The Kit includes the following:
2 - AW-62109-000 Covers;
16 - 8RX3/8THA,SS #8 Sheet Metal Screws - Stainless;
